I find it useful not to dwell or ruminate in thoughts of smoking- in effect remove it from my mind.
Eat sleep watch tv cook do anything to push the thoughts out of your mind.
I never told anyone either of my cessation attempt to avoid discussion and focus on the topic.
I also took 4 days off work in order to go cold Turkey with the mindset it was to give up smoking only and get through the withdrawal phase- so basically said to myself if I want to watch tv I will sleep I exercise I will sleep I will and do the withdrawal on my own without work pressure or family or friends around. That really helped.get all the physical and mental nasties that may come out - out in my own safe space. Worked well for me.
